[R] help with for loop to test for a condition in a vector

[scoyoc]

I want my for loop to test for the presence of a term in a vector and return
a value to a new vector. I'm not writing it correctly though. Here's what I
have...

> testfor = letters[1:5]
> x = c("a", "b", "e", "f", "g")
> result = rep(NA, length(testfor))
> 
> for (i in testfor){
+   v = any(x == testfor[i])
+   result[i] = v
+ }
> 
> result
                a  b  c  d  e 
NA NA NA NA NA NA NA NA NA NA 

I would like to get....

>result
TRUE TRUE TRUE FALSE FALSE

Thanks,
MVS
